Hello Russell!
First you have to find the widget that is directly attached to the table
cell. There is no simple function call since a widget can span more than
one cell in a table. You would need to access the GtkTableChild structure,
but I'm not sure how to do this. You could try whether GtkTable->children
really only stores GtkWidgets like the doc says, or if you're lucky it
stores GtkTableChild's.
When you found the top widget of the desired table cell you have to go
down the tree until you find your GtkEntry. How this is done in detail
depends on the type of widgets you pack between the table and the entry.
GList*      gtk_container_get_children      (GtkContainer *container);
and
GtkWidget*  gtk_bin_get_child               (GtkBin *bin);
can be used for that.
Probably it's easier to store global pointers to the entry widgets you
need to access later.
